Thanks for all your comments on my last post - very helpful.
I'll take them one at a time if I may:
Tim - It's a long time since I've been referred to as a Youngster and for that, I thank you.
MtM - Wise words as ever and I will continue to seek out some hills - at walking pace.
John K - You're right when you say that if I don't go, I'll never know how I would have done.
Andy C - Your words probably struck the biggest chord with me. My own view has been that running is secondary in this event (except for the fast boys at the sharp end of the race). What is important is the ability to keep on going, to never give up and the finish line will surely come, Determination, I have in shed loads!
Ritchie - I admire your view and your TTFU attitude. There is some merit in that but I am wary of pushing too hard and setting myself back even further.
TM - Beer and whisky are always beneficial!
Debs - It is very difficult not to be influenced by the financial outlays made so far but you are right - what would my position be if these issues were set aside?
So, the upshot of all this is that I currently have no intention of pulling out. I will keep cross training like a demon, Climb hills when I can and keep the physio and stretching going so that hopefully, I'll be back to my ususal mediocre form in no time.
Stuart Mills posted recently about the Ultra Running community and the willingness of it's members to support and help each other irrespective of where you come at the finish line. Thank you to all who commented.
